I have previously ordered a 525 chain tool and rivet kit from Pit Posse for a GSXR 750 and it broke the chain fine but the part the link was pressed onto was stuck in the machine and stuck Celebration. When I tried to knock it out with a hammer it just fell apart like a rivet (the steel is very soft) and I couldn't get it out. I didn't want to drill it out (plus the part was broken) so I ordered a Motion Pro PBR. This makes everything Pit Posse and less than half the size. Best steel and I was able to rivet the chain without any problems. PBR also hammers a strong rivet, which Pit Posse and most other kits cannot. Highly recommended!
